This study attempts to understand urban evolution characteristics through suburban development cases considered as a contemporary urban issue. Methods are (1) Urban Expansion Intensity Index (UEII) for the 9 cities in the Korea (1980-2010) & 49 cities in the US, (2) Morphological Spatial Pattern Analysis(MSPA) and Entropy for the developed areas in the Chicago Metro (2019). Results are (1) a suburban development could be understood the universal characteristics, (2) the characteristics of the whole region might be appeared to be in a different direction from the characteristics of its sub-cities. Implications are (1) Suburban expansion can be understood as a functionally well served urban change phenomenon and it is important to focus on the functions of sub-level cities, (2) the urban evolutionary perspective makes a difference from the developmental growth perspective. The extensive empirical studies will be beneficial for better understating of urban evolution.

This article attempted to apply the methodology of film acting as a performance oriented towards socio-cultural meaning to Min-sik Choi's acting. Specifically, the relationship between the body, the face, the audio, the direction and the attitude toward film technology mentioned in the interview dictation of actor Choi Min-sik was analyzed. In conclusion, Min-sik Choi's acting cannot be defined only by method acting, but implies or integrates the typical or avant-garde acting theories such as Stanislavsky, Strasberg, Mayerhold, Brecht and Grotovski. Above all, it is the presentation that expresses the flow of life through movement suggested by S. Kracauer. The feeling of compassion that Choi Min-sik himself emphasizes is in contact with the essence of the film that reproduces the flow of life, and it expands to an intended screen performance with a certain purpose. The screen performance that can be compressed with compassion and the flow of life is expressed by Min-sik Choi's various personas. His persona, transcending good and evil, reflects the present of Korean society.

The study looks a shape of hybrid character in animation and suggests extended discussion to develop the Korean creative characters and to repeat traditional culture that can reproduce in mass media. First, this study considers Jangseung and Dokkaebi that appear frequently in the Korean traditional culture, and prepares a way to try to develop the Korean hybrid characters. To do this, I analyze examples of hybrid characters direction in as-found animation characters, and grasp the meaning of it. Hybrid character is classified as a character produced by mix and combination of shape and a character produced by shape exaggeration. And I shed new light on characters and meanings of Jangseung and Dokkaebi remaining as cultural assets. Through this, the study wants to help handling measure about a problem of character that the Korean animation has. Therefore, this study looks characters of description about imaginary creatures expressed in existing animations, and wants to shed new light on the Korean Jangseung and Dokkaebi regarded as from an object of folk religion and custom, to an object that is possible to use in the Korean traditional character development.

XML is rapidly becoming technologies for information exchange and representation. It causes many research issues such as semantic modeling methods, security, conversion far interoperability with other models, and so on. Especially, the most important issue for its practical application is how to achieve the interoperability between XML model and relational model. Until now, many suggestions have been proposed to achieve it. However several problems still remain. Most of all, the exiting methods do not consider implicit referential integrity relations, and it causes incorrect data delivery. One method to do this has been proposed with the restriction where one semantic is defined as only one same name in a given database. In real database world, this restriction cannot provide the application and extensibility. This paper proposes a noble conversion (RDB-to-XML) algorithm based on the similarity checking technique. The key point of our method is how to find implicit referential integrity relations between different field names presenting one same semantic. To resolve it, we define an enhanced implicity referentiai integrity relations extraction algorithm based on a widely used ontology, WordNet. The proposed conversion algorithm is more practical than the previous-similar approach.

In this study, it propose a proof theory method for expressing and reasoning knowledge in a multiagent environment. Since this method determines logical results in a mechanical way, it has developed as a core field from early AI research. However, since the proposition cannot always be proved in any set of closed sentences, in order for the logical result to be determinable, the range of expression is limited to the sentence in the form of a clause. In addition, the resolution principle, a simple and strong reasoning rule applicable only to clause-type sentences, is applied. Also, since the proof theory can be expressed as a meta predicate, it can be extended to the metalogic of the proof theory. Metalogic can be superior in terms of practicality and efficiency based on improved expressive power over epistemic logic of model theory. To prove this, the semantic method of epistemic logic and the metalogic method of proof theory are applied to the Muddy Children problem, respectively. As a result, it prove that the method of expressing and reasoning knowledge and common knowledge using metalogic in a cooperative multiagent environment is more efficient.

This study examined the structure that can explain the 'gewuzhizhi' as a medical research methodology and how to acquire knowledge from this structure. First, we derive a structure that implies the meaning of 'gewuzhizhi' shown in "Liji" and "daixue" in relation to "xueji" and "shaoyi". It is Xue- gewuzhizhi -'You(游)'. Then, we examined the purpose of the travelling Mt. Hua of Wang Lu, who was a landscape painter and medical researcher and physician and the implication of 'You' in Song Dynasty's painting theory of "Tuhua Jianwenzhi", "Linquan Gaozhi". In the course of the review, I explained the following. First, 'You' in the travelling Mt. Hua of Wang Lu and 'You' in the painting theories of Song Dynasty belongs to the structure of Xue- gewuzhizhi-'You'. Secondly, the meaning of 'gewuzhizhi' in the structure of Xue-gewuzhizhi-'You' was deepened in Song Dynasty. Third, The way in which the 'You' of the Song Dynasty's painting theory is to learn the reason of things is to observe things. Fourthly, the structure of the Xue-gewuzhizhi-'You' was practiced in the painting area in the Song Dynasty, and the field of practice was extended to the study of medicine by the landscape researcher who followed the painting theory of Song Dynasty. Fifth, through the assertion of Wang Lu's 'I take Mt. Hua as my teacher[師]', Wang Lu finds that the source of the recognition lies in nature(Mt. Hua). Through the above, 'gewuzhizhi' shown in "Liji" and "dai xue" is involved in the theory of cultivation and epistemology, and the structure of xue-gewuzhizhi- 'You' involved in epistemology and the method of recognition is found in observation. Through these investigations, I understood logically 'gewuzhizhi' as a method of medical research.

The main purpose of this paper is to identify the spatiality of North Korea and China border regions through investigating the exceptional characteristics of the regions with the concept of positionality, which allows us to realize the relative position between subject and object. Border regions could be identified appropriately by considering the concept of switching positionality, as it is a kind of multiple space in which its sudden closure and opening should be configured in accordance with geopolitical and geoeconomic changes centering around border line. The main arguments of this research concerned with border regions with the concept of switching positionality are fallen into three. Firstly, changes in border regions should be analyzed by investigating more broader contexts and conjunctural perspectives, and even an internal condition stemmed from locality. Secondly, trajectories of border regions could be analyzed by the assemblages of various powers. Finally, the positionality of economic actors should be examined by identifying dynamic relations between geoeconomics and geopolitics. In particular, the concept of positionality has led to a number of insights into discussions on time-space, and spatiality in relational-dialectical, socio-spatial, and power-topological perspectives. Based upon this concept of positionality, the research has identified exceptional characteristics in North Korea and China border regions. It argues that the exceptionality of the region has stemmed from the intersection between the unstability of geopolitical security and various geoeconomic benefits.

The purpose of this study was to explore students' argumentation in perspectives of epistemology and psychology and to find out how teacher can promote students' abilities of developing argumentation. The 60 hours of lessons from the interaction between one science teacher (Mr. Physics, who had 35 years of teaching experience) and his 26 students were observed, transcribed, and analyzed using two different analyzing tools; one is from the perspective of epistemology and the other from the perspective of psychology, which can portray how argumentation is constructed. Mr. Physics created the environment where students could promote the quality of scientific argumentation through explicit teaching strategy, Claim-Evidence Approach. The low level of argumentation was portrayed through examples from students' prior knowledge or experience in the form of an Appeal to the instance operation and the Elaboration reasoning skill. Students' own claims were developed through application of knowledge in a different context in the form of an Induction operation and Generativity reasoning skill. Higher level of argumentation was portrayed through Consistency operation with other knowledge or experience and Explanation reasoning skills based on students' ideas with more active teacher's inputs. The teacher in this study played a role as a helper for students to enact identities as competent "sense makers," as an elaborator rather than evaluator to extend students' ideas, and as a mentor to foster and monitor the students' development of ideas of a higher quality. It is critical for teachers to understand the nature of argumentation, which in turn is connected to their explicit teaching strategy with the aim of providing opportunities where students can understand the science enterprise.

Activity durations retain probabilistic and stochastic natures due to diverse factors causing the delay or acceleration of activity completion. These natures make the final project duration to be a random variable. These factors are the major source of financial risk. Extending the Stochastic Project Scheduling Simulation system (SPSS) developed in previous research; this research presents a method to estimate how the final project duration behaves when activity durations change randomly. The final project cost is estimated by considering the fluctuation of indirect cost, which occurs due to the delay or acceleration of activity completion, along with direct cost assigned to an activity. The final project cost is estimated by considering how indirect cost behaves when activity duration change. The method quantifies the amount of contingency to cover the expected delay of project delivery. It is based on the quantitative analysis to obtain the descriptive statistics from the simulation outputs (final project durations). Existing deterministic scheduling method apply an arbitrary figures to the amount of delay contingency with uncertainty. However, the stochastic method developed in this research allows computing the amount of delay contingency with certainty and certain degree of confidence. An example project is used to illustrate the quantitative analysis method using simulation. When the statistical location and shape of probability distribution functions defining activity durations change, how the final project duration and cost behave are ascertained using automated sensitivity analysis method

This study attempted to examine how we really think about our daily duties, work, and labor, and what it means. In particular, in this study, using the Q-methodology, one of the "qualitative studies," diagnosed and categorized general workers' thoughts about their work and labor. Accordingly, the following analysis results were derived. First, as a result of the analysis, three types were derived, and the types were named as follows based on the Q statement emphasized by each type. emphasizes statements such as 'blessing/happiness', 'rest', 'lover', and 'reward' for work, and labor was named 「Positive Type」. was named as 「Negative Type」 because statements such as 'painfulness', 'the beginning of the day', 'duty', and 'war' were emphasized. In , 'colleagues and friends' and 'learning' were positive, and 'beginning of the day', 'duty', and 'rest' were expressed as negative statements, so it was named as 「Positive Neutral Type」. 'Work' and 'labor', which are indispensable beings in our daily life, are blessings that must be done, happiness, and co-workers and friends, but the value of their existence is possible when appropriate 'resting' is assumed. In addition, Q methodology is expected to be confirmed as an empirical study in the future, as well as usefulness as a hypothesis abductive approach.
